Whakaoti i te 54(2-p)=-14(p+2)

$$54 ( 2 - p ) = - 14 ( p + 2 )$$

Whakaoti mō p

$$p = \frac{17}{5} = 3\frac{2}{5} = 3.4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 54 ki te 2-p.

$$108-54p=-14\left(p+2\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -14 ki te p+2.

$$108-54p=-14p-28$$

Me tāpiri te 14p ki ngā taha e rua.

$$108-54p+14p=-28$$

Pahekotia te -54p me 14p, ka -40p.

$$108-40p=-28$$

Tangohia te 108 mai i ngā taha e rua.

$$-40p=-28-108$$

Tangohia te 108 i te -28, ka -136.

$$-40p=-136$$

Whakawehea ngā taha e rua ki te -40.

$$p=\frac{-136}{-40}$$

Whakahekea te hautanga \frac{-136}{-40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -8.

$$p=\frac{17}{5}$$
